Bug 462917

Application: kmail (5.22.0 (22.12.0))

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.12-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
I've noticed that KMail consistantly crashes when I have en email window open (for editing) and I close the main KMail window (out of habit), then open it again.  Thankfully, I don't appear to actually lose any data when that happens, but it's incredibly annoying and disruptive.

Furthermore, this has been a bug for a while now (at least a year?), but the circumstances that cause it are usually accidental (start writing a new email, take a break to go do something else, close KMail to reduce clutter, then open it again with the email window still open), so I'm only now getting around to reporting it.

(I'm not 100% certain if it's *always* reproducible, so I set reproducibility to "sometimes", but I think it's reproducible *most* of the time.)

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
